Abstract
An apparatus and method are provided for powering an integrated circuit chip with a supply voltage generated externally to the chip. An on-chip clock signal is generated with a ring oscillator fabricated on the integrated circuit chip. The supply voltage is altered as a function of a difference between a frequency of the on-chip clock signal and a reference clock frequency.
